Second , in this paper , we also research the arithmetic of wavelet and fractal , at last give a method to synthesize the two technologies . through experiments testify this method is feasible . choice of filter in wavelet image compression is a critical factor which affects image compression quality 選擇濾波器時(shí),人們一般考慮正交性、對(duì)稱性、正則性、支撐集和消失矩階數(shù)等濾波器本身的性質(zhì),卻很少將他們與圖像紋理特征、濾波器長(zhǎng)度、壓縮比等因素綜合起來(lái)考慮。
People often think about the filter ' s characters of orthogonal , symmetry , regularity , but seldom synthetically think about some factors such as image texture or compression rate . in this paper used the same adaptive arithmetic coder for many filters , analyzed the effect factors synthetically for the best wavelet compression , and give some methods for selecting filter 本文對(duì)多種常見(jiàn)濾波器,采用相同的自適應(yīng)量化編碼方法進(jìn)行實(shí)驗(yàn),研究并分析了選擇濾波器時(shí)應(yīng)該考慮的圖像紋理、濾波器長(zhǎng)度、壓縮比等一些綜合因素,有效解決了在小波圖像壓縮過(guò)程中,如何更好的選擇濾波器的問(wèn)題。
